Why Microsoft is Likely Doomed Based on one Email Folder

Close up of the useless Junk folder in Microsoft Outlook

When you get a piece of spam in Outlook you move it to Junk or block the sender. And then, even if that junk mail is marked as read, the Junk folder has a BOLD MESSAGE COUNT. It's the only folder that does this. I cannot do any other work while I have a bold message count and so I have to switch to the Junk folder and delete the message to get rid of it.

Regular email: read, file, done.

Junk email: recognize as spam, click block sender, confirm that I really want to block the sender, switch to Junk folder, mark as read, delete.

Something is really wrong with this workflow. It's a lens through which you can view the ultimate demise of the company. Sure, Office isn't going away soon and Azure is growing like crazy and SQL Server runs on Linux. But somewhere in Redmond 5,000 people designed a Junk email folder that is the MOST IMPORTANT folder in Outlook. The rest were presumably too busy making Windows Update worse to stop this.

My Google experience is that I really don't get much spam. The spam that I do get is hidden from me unless I actually need to rifle through it for some reason. On the occasion I actually get legitimate junk I just flag it as such and never have to touch it or it's ilk again.

Email Alerts for new Referers in Google Analytics using Apps Script

Referral Traffic in Google Analytics

It's useful to know when you have a new website referrer. Google Analytics is plagued with spam referral and you want to filter this out of reporting as quickly as possible to stop it from skewing your data. It's also helpful to be able to respond quickly to new referral traffic - maybe leave a comment or promote the new link on social media.

The script below will send you a daily email with links to any new referrers.

var TableId = 'ga:your-view-id';
var SendEmailTo = 'your-email-address';

function main() {
  var scriptProperties = PropertiesService.getScriptProperties();
  var currentProps = scriptProperties.getProperties();
  var anythingNew = false;
  var newText = '';
  var yesterday = Utilities.formatDate(new Date(new Date().getTime() - 24 * 60 * 60 * 1000), Session.getTimeZone(), 'yyyy-MM-dd');
  var options = {
    'dimensions': 'ga:fullReferrer',
    'filters': 'ga:medium==referral',
    'max-results': 20000
  var report = Analytics.Data.Ga.get(TableId, yesterday, yesterday, 'ga:sessions', options);
  if (report.rows) {
    for (var i = 0; i < report.totalResults; i++) {
      if (!(report.rows[i][0] in currentProps)) {
        Logger.log('Found new referrer: ' + report.rows[i][0]);
        scriptProperties.setProperty(report.rows[i][0], report.rows[i][1]);
        anythingNew = true;
        newText += 'New referrer: ' + report.rows[i][0] + '\r\n';
  } else {
    Logger.log('GA report is empty');
  if (anythingNew) {
    MailApp.sendEmail(SendEmailTo, 'Found new referrers for ' + TableId + ' on ' + new Date(), newText);

Start a new apps script project in Google Drive and paste in the code. At the top enter the view ID that you want to monitor and the email address that should receive reports.

Choose Advanced Google Services from the Resources menu and switch on the Google Analytics API. Then click the Google API Console link and enable the Google Analytics API there as well.

Finally pick Current project's triggers from the Edit menu and trigger the main function daily at a convenient time.

This script saves known referrers in script properties. For a site with lots of traffic this may run out of space in which case you might need to switch this out and write known referrers to a sheet instead.

Reading and Writing Office 365 Excel from a Console app using the Microsoft.Graph C# Client API

I needed a console app that reads some inputs from an online Excel workbook, does some processing and then writes back the results to a different worksheet. Because I enjoy pain I decided to use the thinly documented new Microsoft.Graph client library. The sample code below assumes that you have a work or education Office 365 subscription.

using System;
using System.Collections.Generic;
using System.Globalization;
using System.IO;
using System.Linq;
using System.Net.Http.Headers;
using System.Threading.Tasks;
using Microsoft.Graph;
using Microsoft.IdentityModel.Clients.ActiveDirectory;
using Newtonsoft.Json.Linq;

namespace Excel365Test
    /// <summary>
    /// 1) Install Microsoft.Graph NuGet Package
    /// 2) Install Microsoft.IdentityModel.Clients.ActiveDirectory NuGet Package
    /// 3) Register app at - need app ID and redirct URL below
    /// </summary>
    class Program
        static void Main(string[] args)
            TokenCache tokenCache = new TokenCache();

            // load tokens from file 
            string tokenPath = Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.LocalApplicationData), "Excel365Test");
            if (!Directory.Exists(tokenPath)) { Directory.CreateDirectory(tokenPath); }
            tokenPath = Path.Combine(tokenPath, "tokens.dat");
            if (System.IO.File.Exists(tokenPath))

            // this is the OAUTH 2.0 TOKEN ENDPOINT from -> Azure Active Directory -> App Registratuons -> End Points
            var authenticationContext = new AuthenticationContext("", tokenCache);

            // only prompt when needed, you'll get a UI the first time you run
            var platformParametes = new PlatformParameters(PromptBehavior.Auto);

            var authenticationResult = authenticationContext.AcquireTokenAsync("",
                "your-app-id",     // Application ID from
                new Uri("http://some.redirect.thing/"),         // Made up redirect URL, also from
            string token = authenticationResult.AccessToken;

            // save token so we don't need to re-authorize
            System.IO.File.WriteAllBytes(tokenPath, tokenCache.Serialize());
            // use the token with Microsoft.Graph calls
            GraphServiceClient client = new GraphServiceClient(new DelegateAuthenticationProvider(
            (requestMessage) =>
                requestMessage.Headers.Authorization = new AuthenticationHeaderValue("bearer", token);

                return Task.FromResult(0);

            // test reading from a sheet - in this case I have a test worksheet with a two column table for name/value pairs
            var readSheet = client.Me.Drive.Items["your-workbook-id"].Workbook.Worksheets["test"];
            var readTables = readSheet.Tables.Request().GetAsync().Result;
            string readTableId = readTables[0].Name;
            var table = readSheet.Tables[readTableId].Rows.Request().GetAsync().Result;
            // convert page to a dictionary... this doesn't handle pagination
            Dictionary<stringdecimal> tableValues = table.CurrentPage.ToDictionary(r => r.Values.First.First.ToString(), 
                r => Convert.ToDecimal(r.Values.First.Last, CultureInfo.InvariantCulture));

            // test adding a row to a table with four columns
            // sadly it seems you need this exact format, a regular JArray or JObject fails

            WorkbookTableRow newRow = new WorkbookTableRow
                Values = JArray.Parse("[[\"1\",\"2\",\"3\",\"4\"]]")
            var outputSheet = client.Me.Drive.Items["your-workbook-id"].Workbook.Worksheets["data"];
            var outputTables = outputSheet.Tables.Request().GetAsync().Result;
            string outputTableId = outputTables[0].Name;
            var outputResult = outputSheet.Tables[outputTableId].Rows.Request().AddAsync(newRow).Result;

            // the excel unit tests seem to be the most useful documentation right now:

Paste the code into a new console project and then follow the instructions at the top to add the necessary NuGet packages. You'll also need to register an application at You want a Native application and you'll need the Application ID and the redirect URL (just make up some non-routable URL for this). Under Required Permissions for the app you should add read and write files delegated permissions for the Microsoft Graph API.

Hope this saves you a few hours. Comment below if you need a more detailed explanation for any of the above.
